HAY-STAOKER.

Patented Jan. 8, 1907.

Application filed January 27, 1906. SerialNo. 298,219.

To all whom it may concern:

Be it known that 1, WILLIAM D. McATLIN, a citizen of the United States, residing at Tullvania, in the county of Macon and State of Missouri have invented certain new and useful Improvements in Hay-Stackers, of which the following is a specification.

The object of my invention is to provide an improved hay-stacker designed to receive a.

predetermined amount of hay and throw it upon a stack or into a wagon.

The present embodiment of my improved hay-stacker is illustrated in connection with an improved construction of horse-power which is the basis of another application, a divisional from this application, such other application being Serial No. 311,580, filed on or about the l3thday of April, 1906.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings, in which Figure 1 is a top plan view of my invention. Fig. 2 is a detail perspective view illustrating one set of sectional braces or straps 12. Fig. 3 is a perspective view of the hay-stacker proper, with parts in discharging or upright position. Fig. 4 is a transverse sectional view of the horse-power mechanism designed for use with the hay-stacker of my invention, the section being taken approximately on the line x w of Fig. 8, the parts being in normal position. Fig. 5 is a sectional view of the hay-stacker with the parts of the fork extended. Fig. 6 is a detail perspective view of the lower end of one of the fork-arms and the adjustable brace therefor. Fig. 7 is a detail perspective view of the tumbling-rod and its adjustable mounting.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The stacker proper comprises a framework 1, including two side bars 2, that constitute, in effect, sled-runners upon which the stacker may be moved from one place to another. The framework is provided with suitable diagonal braces, as shown. The shaft 3 is j ournaled-at its ends in cross-bars 4 of the framework 1 and extends longitudinally thereof and is mounted to rock back and forth upon its longitudinal axis. The shaft 3 has rigidly secured to it two standards 5, one near each end of the shaft. The standards 5 are each formed of two spaced-apart members 5*, extending radially from the shaft and rigidly secured thereon by means of a box 5*. Be-' tween the free ends of the spaced members 5 of the standards 5 are slidably mounted bars 6, which also extend radially, as shown, and are preferably guided in a longitudinal movement with respect to the standards by means of loops 7 and 8, embracing the parts, as shown. The bars 6 at their outer ends carry a series of tines 9, which are all rigidly connected together. The transverse rod 10 extends across and is secured to the rear end of the tines 9, and upon this rod there is secured a second set of tines 11. The tines 11, in combination with the tines 9, constitute the hay-receiving portion of the stacker or the fork upon which the hay is deposited preparatory to being thrown on the stack or into a wagon or the like. The set of tines 11 is pivotally mounted on the shaft 10, so as to be permitted to move toward and from the set of tines 9 and to limit the movement of the tines 11 in one direction I have provided two pairs of. straps 12. One strap of each pair is connected to a diagonal brace 13, ex-

tending from one of the bars 6 to the shaft 10, while the other strap of the said pair is attached to a cross-bar 11*, secured tothe tines 11. Both straps of each pair are provided with slotted ends 14, that are slidably connected together, so that the pairs of straps may be extended to a certain definite limit, and thereby permit a proportionate movement of the pivoted tines 11.

As has before been stated, the bars 6 are longitudinally slidable with respect to the standards 5 which carry them, and by this means the hay-receiving fork is rendered extensible. When the bars 6 are slid outwardly on the standards 5, they may be retainedrigidly in such extended position by means of stirrups 15, that are pivotally secured to the loops 7 and are designed to turn over into engagementwith the outer ends of the outer most members-5 ofthe standards 5. Trussrods 16 are secured .at one end in posts 17, mounted in the outer ends of the bars 6, and the other ends of said truss-rods 16 are provided with loops 18. From the bases of the standards 5 there project two posts 19, on

each of which there is mounted an eccentricall y-fulcrumed hand-lever 19", each of which is provided with a notch 19*, designed for the accommodation of the loops 18. From the foregoing it is to be understood that when the hay-receiving fork is extended to its limit the loops 18 are in the notches 19 of the levers 19, and the latter are then turned down or inwardly past their centers to snap into locked position, and thereby securely hold the truss-rods in taut position. Each trussrod 16 comprises two members 16 and 16 The member 16 is provided at one end with a loop 18, before described, and is provided at its other end with an eye 20, slidably engaging the other member 16 When the fork is extended and the loop 18 engaged by the hand-lever 19*, before mentioned, the

eye 20 of the member 16" will bring up against the shoulder 20 on the member 16 When,'on the other hand, it is desired to hold the fork in a radially-contracted position at the inner limit of the relative movement with respect to the standards 5, another loop 21, formed on the member 16*, is detachably connected to the hand-levers 19 while the other members 16 may be entirely free from said levers. It will thusbe seen that each truss-rod 16 is adjustable or extensible in character to accommodate itself to two different positions (contracted and extended) of the fork with respect to its standards.

22 designates springs the action of which tends to return the hay-receiving fork to an approximately vertical position to throw the load of hay thereon onto the stacker into a wagon. In the present instance the springs 22 are arranged in two pairs, one pair for each of the standards 5. Also in the present instance each spring comprises. coiled por tions 22, wound around the shaft 3 or a sleeve, boss, or the like on said shaft, and two diverging ends 22", one of which is connected to a side bar 2 of the framework 1 or some other specific part of the framework, while the other end is connected'to a spool, thimble, or roller 23, mounted between the spaced members 5" of the standards 5 andguided therein by means of side plates 23. As shown in the drawings, the osts 19 preferably extend entirely throug the standards and have secured to their ends diagonal braces 24. The braces 24 are also secured at opposite, ends to the standards 5 at the outer ends of the latter. 1

In the practical operation of the stacker the framework 1 is moved to the desired point in the field and the hay-receiving fork is adjusted to the desired extension. By

means of my improved horse-p0 Wer and tumbling-rod, which I shall shortly describe, the shaft 3 is rocked back and forth. It is first turned in one direction against the action of the springs 22', so as to carry the hay-receiving fork downwardly in such a position relative to the ground that the hay may be slipped thereon. When this operation has been completed, theshaft 3 is turned backwardly in a direction to relieve the s rings 22 of their tension and in a direction a so to lift the hay-receiving fork so that it will deposit its load upon the stack or in a wagon or the like. It is to be particularly noted that the tension of the springs 22 is to raise the hayreceiving fork. horses is equalized, as the exertion that is required to depress the hay-receiving fork when moving the same in a downward direction is substantially compensated for by the springs 22 when force is exerted to raise the loaded fork into position to dump its load.

The tumbling-rod construction for actuating the stacker proper is, according to the present embodiment of my invention, incorporated in a horse-power forming the basis of my other application before referred to and which I shall now proceed to describe.

Upon the framework 25,- consisting of side Hence the strain upon the bars and sled-runners 26, connected to crossbars 27 by diagonal members 28, there is mounted a carriage 29. I The carriage 29 is mounted to slide back and forth on the framework 25, and in the present instance the means whereby this movement is provided comprises sleeves 30, that encircle and are slidably mounted upon the cross-bars 27. To effect the movement or actuation of the carriage, I have provided a screw-rod 31, mounted to turn in a suitable bearing 32 on one of the side bars 26, but held from longitudinal movement thereon, thesaid screw- .rod working through a correspondinglyformed bearing 33 in a cross-bar 34 of the, carriage. By means of a spanner or some similar tool applied to the polygonal nut 3.5 of the screw-rod the latter may be turned'so as to move the carriage in one direction or another upon the framework 25.

TCO

The tumbling-rod 36 is connected byguniversal joints 37 to the shaft 3 of the stacker proper, the said joints being preferably gimbaljoints, one or more spindles of which are detachable, so that the parts may be disconnected 'or coupled together whenever desired. Connecting-rod 38 may be also introduced into this gearing, so that the tumblingrod 36 may be located at a convenient distance from the stacker proper.

The tongue .TIO

39 of the tumbling-rod 36 is preferably bifurcated at one end to encircle the tumblingrod and is pivotally connected thereto, so that it may rock the same. from side to side. The tongue 39 is provided at itsv other end with a boxing 40, in which it is mounted to freely turn both axially and longitudinally; The boxing 40 is provided at its sides with trunnions 41, which are pivotally mounted in a sliding cross-head 42. The cross-head 42 is mounted in and between guide-bars 43 and is susceptible to movement thereon, and

it is formed at one end with a transverse bearing 44, in which a threaded adj usting-rod 45 is mounted. The rod 45 is also mounted with a swivel connection in a bearing 45*, secured to the bars 43 near one end of the latter. Near the opposite end of the bars 43 there is pivotally mounted a lead-pole-46, arranged to be swung in a verticalplane, so that it may extend out horizontally or be swung up into a vertical position out. of the way. The guide-bars 43 are rigidly secured to a ring 47, which is mounted to rotate upon an annulus 48, supported on the carriage 29 and positioned horizontally. Also rigidly secured to the ring-47 are spaced-apart beams 50, between which a lever 51 is mounted to slide longitudinally, so that it may be extended more or less. The lever 51 is the lever to which the horse or horses are attached to actuate the horse-power. Braces 52 and 53 are secured to the beams 50 and the beams 43, so as to render the parts rigid.

When the horse-power is coupled to the stacker roper and the former is turned by means of the lever 51, it is evident that the tongue of the tumbling-rod will turn the shaft 3 of the stacker proper in one direction through one-half the revolution or turning movement of the horse-power and will then turn the said shaft 3 backward during the remaining half of said movement. By this means as the horses move around the framework 25 the hay-receiving fork will be first lowered to receive its load and then raised to de osit the same.

t is to be particularly noted that the carriage 29 may be moved to different positions along the supporting-framework 25, so as to shift the carriage to compensate with the position of the framework 1 and the shaft 3, so that the tumbling-rod and said shaft may be always arranged in the proper alinement. It is also to be understood that the cross-head for the tongue of the tumbling-rod may be shifted or adjusted to different positions, so as to vary the pitch of the tumbling-rod, and consequently also the pitch or throw of the hay-receiving fork.
